Mark 14:5

And being in Bethany in the house of Simon the leper, as he sat at meat, there came a woman having an alabaster box of ointment of spikenard very precious; and she brake the box, and poured it on his head.

And there were some that had indignation within themselves, and said, Why was this waste of the ointment made?

And Jesus said, Let her alone; why trouble ye her? she hath wrought a good work on me.

For ye have the poor with you always, and whensoever ye will ye may do them good: but me ye have not always.
